Description
Impact
matrix-js-sdk before 38.2.0 has insufficient validation of room predecessor links in `MatrixClient::getJoinedRooms`, allowing a remote attacker to attempt to replace a tombstoned room with an unrelated attacker-supplied room.
Patches
The issue has been patched and users should upgrade to 38.2.0.
Workarounds
Avoid using `MatrixClient::getJoinedRooms` in favour of `getRooms()` and filtering upgraded rooms separately.
